If you are behind NAT and are going to use the Edgerouter subnet in addition to an existing subnet (behind another router) also some setting changes are required. These settings are only recommended in this scenerio.

Go to First top menu Firewall/NAT tab.

Go to Second top menu Firewall Policies.

Edit WAN_LOCAL at the right menu item Actions > Edit RuleSet

From the Configuration tab, Change the radio button to “Accept” and click “Save Ruleset”.

Warning

Be sure you want to do this and that you are behind either a firewall appliance or another router.

This will look different depending on the other router that you might have and what IP range you use.

A static route is needed on the other router in order for traffic to reach your FusionPBX installation and is only needed if the Edgerouter is the double NAT.

Scenerio: Router A is the primary router that has a public IP address and a LAN subnet of 10.10.2.1. From this pool of IP addresses, the Edgerouter gets IP 10.10.2.209. Be sure that router A has DHCP reservation or the ability to make 10.10.2.209 a static IP.

Router A Router name: This is a label for organizing.

Router A Destination IP address: 192.168.1.38 This is the IP that the Edgerouter gave to your FusionPBX install.

Router A Subnet mask: 255.255.255.0 is the subnet mask used in this example.

Gateway: 10.10.2.209 is the IP Router A gave to the Edgerouter WAN eth0.

Interface: LAN is a label on Router A to show it’s a local area network address.
